Design And Application Of Agricultural Remote Sensing Monitoring System Based On ArcGIS Engine

The remote sensing technology plays a very important role in the agricultural crop information monitoring,agricultural resource monitoring,agricultural disaster detection and so on,but the agricultural resource information obtained by using remote sensing technology,there are many kinds,large data,the great dispersion,controlled lowly,storage difficulty,only using advanced information technology to manage the agricultural remote sensing information,to allocate resources rationed,to provide guidance for macro decision.Firstly,this thesis analysis the characteristics,development process and actual application of geographic information system(GIS)'s structure is described,the core technology and features of agricultural resource information system(ARIS),and the application status at home and abroad is discussed.Then it introduces the concept,features,application and the analysis of platform of GIS,focus on researching the GIS's data type and structure,the composite layer,collection and input of information and maps,database management,analysis and expression etc..Described in details of the ArcGIS Engine's controls,tools and object library of the three components of the content,as well as the development of the two types of ArcGIS Engine.The Oracle and SDE will be used to establish the spatial database,the Visual Studio is used to develope ArcGIS Engine by twice,the strong portability and easy operation of the agricultural remote sensing information management system is established.This thesis designs the overall of agricultural remote sensing information management system,achieve data preprocessing,growth monitoring,yield estimation,environmental monitoring,disaster monitoring system,achieve efficient management of massive agricultural remote sensing data.The designed and established of the system database is used to realize the integrated management of agricultural remote sensing database.Used the applied and designed system,process the soil erosion and grassland agricultural remote sensing data obtained by actual project,in-depth analysis of the situation of soil erosion and grassland,provide the guidance of macro decision for the agricultural management.
